Answer:

sum of all no -4950 and 13th term is 126.

Step-by-step explanation:

Ap of the given 50-250 divisible by 6 numbers is

54,60,66.......246.

Here, a=54,d=6 and ln=246{here on is last no}

so using formula, ln=a+(n-1)d

then,

246=54+(n-1)6...........

from here value of n will come.

then, using formula , Sn=n/2(a+l)

then from here sum of ap will come.

then, to find 13th term...?

use formula, a13=a+(n-1)d where a=54,n=13,d=6

so, you will get your answer
